django select extremely slow on large table

Dear List, I'm trying to run a simple select on a very large Oracle table (1500 million records). I create a standard django model: -- class Marker(models.Model): marker_id = SYSGUID16Field(primary_key=True) # This field type is a guess. markid = models.CharField(uniqu

To many calculations in the from_db_value function. Need optimizations. And what about query limitations: 1.5b is really needed? class SYSGUID16Field(models.Field): default_error_messages = { 'invalid': "'%(value)s' is not a valid SYS_GUID." } description = "A connector to the SYS_GUID

Thanks you for your response Unfortunately, yes, the 1.5b records is not something I have control over. I agree the SYSGUID field needs working. However, if I change this field to any other field type, the query still takes over 40 seconds. class Marker(models.Model): marker_id = models.Binar

Slow test startup under Django 1.7

I'm in the process of converting a large legacy app from Django 1.5 to 1.7. I've got all the tests passing, so I'm researching an issue I noticed during the course of my work: Test startup takes MUCH longer under Django 1.7 than it did under 1.5. I've got a test that, when run by itself, took a

Re: Slow test startup under Django 1.7

Hey Warren, this is a known problem in 1.7. It is fixed in 1.8 (see https://code.djangoproject.com/ticket/23745). Unfortunately, the changes made to reduce the amount of get_models() and render() calls are too invasive to backport them to 1.7. If you have the time, could you try running your p

Re: Accessing Django test client in setUpClass

Hi Nicole, (I've added this answer to SO as well) Short answer is no - but that's not the end of the story. self.client is a convenience that is configured as part of the "pre-test" sequence. This means it is configured on a per-test basis; so you can use it in setUp(), but not setUpClass(). Ho

Re: OneToOne field versus model inheritance

Hi, Django doesn't really provide a way to create a subclass from an already existing object in the admin. It's actually pretty hard to do even in the code. So for that reason I'd recommend the non subclass with the OneToOneField. Actually, if I were doing it, this is what I would do: class U

Hi, 1.5b rows is rather big data. Could you test what .values() or .values_list() produces in terms of speed. also print qs might actually pull in all selected records in Python memory so it may take a while to constuct bunch of objects. On Thu, 22 Jan 2015 07:32:36 -0800 (PST) Joris Benschop

Re: django select extremely slow on large table

How many results do you typically get back from that query? It sounds like the DB is highly optimized if you can gather results from tables that large that quickly running the query outside of Django. If you are returning a large dataset, then it is more likely that Django is furiously coercing ev
